Power consumption and heat dissipation

Power consumption and heat dissipation specifications are available for multiple configurations. To review
available specifications, go to http://www.hp.com/go/quickspecs.
To reach zero power consumption, unplug the workstation from the power outlet or use a power strip with an
on/off switch. For additional information about power-saving features, see the operating system installation
instructions.
This product is in compliance with U.S. Executive Order 13221 (FEMP).

Resetting the power supply

If an overload triggers the power supply overload protection, power is immediately disconnected.
To reset the power supply:
1. Disconnect the power cord from the workstation.
2. Determine what caused the overload, and fix the problem. For troubleshooting information, see
Diagnostics and troubleshooting on page
3. Reconnect the power cord, and restart the workstation.
When you turn off the workstation through the operating system, power consumption falls below what is
considered low power consumption but does not reach zero. Power consumption only reaches zero when you
unplug the workstation from the power outlet.
